[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] Reference Figure 1 and Figure 2As shown, a woven bag, also known as a snakeskin bag, is a type of plastic bag used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. Most of the existing woven bags need to go through the processes of sewing and pressing to ensure that the woven bags are in a relatively streamlined state during the processing. In the existing flattening process, most of them need to be controlled manually, and the flattening of the woven bags during transportation will cause the woven bags to be affected by both pressure and transmission force, resulting in wrinkles at the bottom of the woven bags. In order to solve such problems, a plastic woven bag flattening device is proposed, including a flattening frame 1 and a processing groove 13 opened in the flattening frame 1, a transmission member 12 for transmitting the plastic woven bag is provided at the bottom of the processing groove 13, a flattening member 2 is provided on the upper side of the transmission member 12, and the flattening member 2 includes a mounting frame 15 provided on both sides of the top of the processing groove 13, and a flattening mounting seat 21 is provided on the lower side of the mounting frame 15 for sliding up and down, and a plurality of flattening mounting seats 21 are opened in the bottom of the flattening mounting seat 21. The guide slide groove 212 has a guide slide rod 213 which slides horizontally in the guide slide groove 212. A pressure plate 221 is provided at the bottom of the guide slide rod 213, and a pressure groove is formed between the pressure plate 221 and the transmission member 12 for the woven bag to pass through in an orderly manner for flattening. A reset member 22 is provided on one side of the guide slide rod 213 for sliding and resetting the pressure plate 221. The flattening frame 1, the processing groove 13 and the transmission member 12 are arranged to achieve the purpose of flattening the woven bag in a stable environment while orderly transmitting the woven bag. The installation frame 15, the flattening installation seat 21 and the pressure plate 221 in the flattening member 2 can achieve the purpose of enabling the pressure plate 221 to press down to adapt to woven bags of different thicknesses for flattening. The installation of the guide slide rod 213 and the guide slide groove 212 ensures that the pressure plate 221 can move synchronously with the transmission member 12 while flattening the woven bag to avoid wrinkles in the woven bag. Similarly, the reset member 22 is arranged to reset the above-mentioned pressure plate 221 after flattening.

[0022] It should be noted that the specific process in which the above-mentioned woven bag is prone to wrinkles during the flattening process is as follows: when the pressure plate 221 exerts a downward pressing force on the woven bag, the woven bag is in a horizontal transmission and sliding state on the transmission member 12. If the pressure plate 221 is fixed at this time, wrinkles will appear at the bottom of the woven bag, thereby causing the flattening effect of the woven bag to deteriorate. In order to solve this type of problem, in this embodiment, the setting of the guide groove 212 and the guide rod 213 can achieve the effect of enabling the pressure plate 221 to slide horizontally for a short distance along with the transmission member 12 during the process of flattening the woven bag, and the pressure plate 221 can be reset after being lifted upward.

[0023] Furthermore, the specific structure of the above-mentioned reset member 22 is as follows: the reset member 22 includes a fixed block 211 arranged at the bottom of the flattening mounting seat 21, and a limiting rod 214 is provided on one side surface of the fixed block 211, and the limiting rod 214 extends to the side close to the guide slide rod 213 and passes through the guide slide rod 213, and a reset spring 215 for resetting the guide slide rod 213 is provided between the guide slide rod 213 and the fixed block 211; through the setting of the reset spring 215, when the guide slide rod 213 slides to the right in the guide slide groove 212, the reset spring 215 is stretched to form a contraction force, and when the flattening is lifted upward, the reset spring 215 will drive the pressure plate 221 to reset, thereby ensuring the purpose of subsequent orderly flattening of the woven bag.

[0024] Additionally, in the present embodiment, the pressing plates 221 are provided in three groups, and most areas of the entire woven bag can be flattened by providing three groups of pressing plates 221 .

[0025] It should also be noted that the transmission member 12 may specifically be a transmission component such as a chain plate.

[0026] Furthermore, the driving source for the above-mentioned pressing plate 221 to slide up and down is: a driving member 23 for driving the flattening mounting seat 21 to slide up and down is provided on the upper side of the flattening mounting seat 21, and the driving member 23 includes a telescopic cylinder 231 arranged on the top of the mounting frame 15, and the output end of the telescopic cylinder 231 extends downward and is arranged on the top of the flattening mounting seat 21; through the operation of the telescopic cylinder 231, the output end can be telescoped to achieve the purpose of driving the flattening mounting seat 21 to slide up and down, thereby achieving the purpose of making the pressing plate 221 slide up and down, thereby gradually approaching the woven bag to flatten the woven bag.

[0027] Additionally, in order to make the flattening mounting seat 21 and the pressure plate 221 more stable during the up and down sliding process, in this embodiment, a guide sliding pillar 24 is provided between the flattening mounting seat 21 and the mounting frame 15 to ensure the vertical and stable sliding of the flattening mounting seat 21; the setting of the guide sliding pillar 24 can achieve the purpose of making the flattening mounting seat 21 and the pressure plate 221 more stable during the up and down sliding process.

[0028] It is worth mentioning that in order to allow the woven bag to better enter the lower side of the pressing plate 221, in this embodiment, the pressing plate 221 is provided with a buffer arc plate 14 on one side of the front section of the transmission member 12, and one side of the buffer arc plate 14 is gradually arranged in an arc shape from top to bottom toward the transmission direction of the woven bag; through the setting of the buffer arc plate 14, the woven bag in the expanded or opened state can be flattened in an orderly manner along the arc surface of the buffer arc plate 14, thereby achieving subsequent flattening.

[0029] It should be noted that, in order to protect the surface of the woven bag during the flattening process, in this embodiment, a protective pad 2211 is provided at the bottom of the pressing plate 221 .

[0030] Furthermore, in order to make the entire flattening frame 1 more stably arranged, in this embodiment, a support frame 11 for supporting the flattening frame 1 is provided at the bottom of the flattening frame 1; the arrangement of the support frame 11 can achieve the purpose of making the flattening frame 1 more stably arranged on the ground.

[0031] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
